I have read the buyers guide and found it very informative.
but why do you comment on the vendors, any past history I should know about? (I live 100miles away!)
Never heard of the vendor. Generally speaking when purchasing a car such as this it is much better (and much safer) buying from a private enthusiat who has meticulously looked after his pride and joy, or an independent specialist who is fully aware of the provenance of Alfas in general and this Alfa Romeo in particular.
Generally when such an Alfa appears in this kind of venue, either it's been bought at auction at a knock-down price, or the previous owner has dumped it (sorry part-ex'd it) on the vendor knowing that horrendous bills are around the corner.
As I said though it could be clean and absolutely immaculate. If you know nothing of these Alfas, you must take a specialist with you to look it over. Total madness if you don't.
OK taken a look at the vendor's website. Y 2001 so registered from March 2001, one of the first batch of 24v Spiders in the UK. Paintwork looks good, front red brake calipers have faded badly (this is normal), interior looks ok. Says it has dealer/specialist history. You need to check this meticulously, and ask whether:
1) Any suspension work has been done - front and rear bushes/arms/shocks prone to wear, rear arms especially, if not seen to this will damage rear aluminium subframe, meaning £££££££££££££££££££££
2) Timing belt/tensioner/idler nearly due (should be done every 60,000 miles/5 years). Must be done now since belts can break early, if not budget £600 minimum from specialist.
3) Oil cooler pipes corrode like no tomorrow - has this job been done?
I'll let the buyers guide do the rest.
